Seven Years' War

The Seven Years War was a global war, encompassing the continents of North America, South America, Europe, Africa, and Asia. It has often been called World War 0 due to it's massive scale. The combatants of the war were: Great Britain, the Iroquois Confederacy, Prussia, Portugal, Brunswick-Wolfenbuttel, Hesse Kassel, Schaumburg-Lippe, France, Abenaki Confederacy, the Holy Roman Empire, Russia, Kalmyk Khanate, Spain, Sweden, and the Mughal Empire. The war first began in North America, in 1754, over territorial disputes in the Ohio River Valley. The war didn't officially begin in Europe until May 1756. Austria desired to take back Silesia, which they lost in the Austrian War of Succession. France and Austria, worried about Britain's and Prussia's growing power, put aside their differences and formed an alliance. Britain then aligned with Prussia. The war in Europe lasted 7 years, ending in 1763 in a British-Prussian victory. 578,588 people were killed by the war. The war left Prussia and Britain as major powers.
